Detection of buildings in observing images using map information

Many GPSs have been introduced into our daily life. It is very convenient to visit some places, but there is some uncertainty to recognize the exact place to be visited. Here, to solve this uncertainty, an attempt to recognize the roads and the building in the real view using the information on a map has been introduced. The system shows the ways to the destination and points the target building in the view of a walker. It enables to correct the error of the GPS and increase the certainty to recognize the building to be visited.
